ELLIGOT D. AVERELL, OF BROOKLYN, NEW YORK.

FILE FOR INVOICES, LETTERS, BONDS, 80C.

SPECIFICATION forming part of Letters Patent No. 273,797, dated March 13, 1883.

Application filed May 26, 1882. (No model.)

To all whom it may concern Be it known that I, ELLICO'I D. AVERELL, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and Improved File for Invoices, Letters, Bonds, &c., of which the following is a specification.

Bound files for letters and other matter in which the leaves are gummed are objectionable for the reason that the gum is not protected or covered in any way, and if a leaf becomes accidentally dampened it will stick to the matter upon the opposite leaf and cause great annoyance, besides destroying the filed papers.

. The object of myinvention is to avoid these difficulties; and to this end my invention consists in a tile composed of several leaves, and having attached to each leaf two or more flaps which are loose at one edge and are gummed on the inner or under side only, and which are secured to the leaf at intervals from one side to the other thereof. In the accompanying drawings, Figure 1 represents a perspective view of my improved file, showing a leaf adapted to receive letters or invoices; and Fig. 2 represents a perspective view of a leaf of such file adapted to receive bonds.

Similar letters of reference designate corresponding parts in both figures.

Referring first to Fig. 1, A designates a bound file of ordinary form, and A designates one leaf thereof, adapted to receive invoices, letters, and other papers which it is desired to file securely.

B designates paper flaps, which are gum med upon their inner or under sides, which lie next the leaf, and they are secured to the leaf along one edge-in this instance the upper edgeand are secured to the leaf at intervals from one side [0 the other. These flaps lie close to the leaf and will not be liable to curl up, so as to expose their gummed sides; but in the drawings I have represented one or two of the flaps as curled up to show on which edge they are free.

0 designates a letter, invoice, or other paper which is filed.

. To file the letter or paper all that is necessary is to run the tongue along the edge or margin thereof to slightly moisten it, and then place the moistened margin under one of the flaps B and press the flap down upon it. By this means the letter or paper is securely attached to the flap, and may be turned up, as shown, so as to enable both sides to be easily read.

It will be seen that by these flaps,gummed on the inner or under side, any possibility of the gum being accidentally dampened, and thus sticking one leaf to the opposite leaf or to the matter filed thereon, is avoided. The leaf A may be numbered opposite the several flaps B, and these numbers may be used in indexing the filed papers.

The file may be made up with as many of its leaves provided with flaps, arranged as shown in Fig. l, as is desirable; but certain leaves may be provided with flaps arranged like the flaps on the leaf A. (Shown in Fig. 2) This leaf is designed for fiTi'ng bonds and their coupons, and near the top and bottom of the leaf are two long flaps, B B", which are reversed in position-that is, the upper flap, B, is gummed to the leaf along its upperedge or margin, and the lower flap, B is gummed to the leaf along iis lower edge or margin.

In filing a bond the opposite edge portions or margins are moistened in the mouth and slipped under the loose edges of the upper and lower fiaps, B B which are then pressed down upon them. On one side of the leaf A are short flaps B, like those shown in Fig. 1, which are designed for filing the bond-coupons.

It will be seen that by my invention I provide a very neat and desirable file,.and one which is especially advantageous, because all the gummed surfaces are protected and cannot he accidentally dampened and become stuck together.

I do not claim as of my invention a file-envelope having a series of flaps out along one edge and gummed on their upper sides, said flaps being adapted to be folded over and stuck to letters or papers to secure them; but

What I claim as my invention, and dcsireto secure by Letters Patent, is-

A file composed of several leaves, and having attached to each leaf two or more flaps which are loose at one edge and are gummed on the inner or under side only, and which are secured to the leaf at intervals from one side to the other side thereof, substantially as and for the purpose specified.

E. D. AVERELL.
